[The effect of long-term ionizing radiation exposure on retinal function].
An experimental investigation designed to study the nervous tunic of eyeball of those animals who had been exposed to low levels of radiation for a long time revealed dystrophic-destructive changes in cellular elements of the above tunic. Its ganglial layer exhibited most marked changes such as destruction of gangliocytes against the background of pronounced pericelmomer edema. Changes in the system of photoreceptors were characterized by suppression of protein-synthesizing function of cells and, to a lesser extent, energy-producing one. An important observation is to our mind practically complete absence of processes of intracellular regeneration, which fact is a bad prognostic sign in respect of recovery of morphofunctional status of retina of the eye. Probability of development of dystrophic events in retina of those individuals having been under combined exposure to low levels of radiation gets higher.
